I can confirm that Mesh doesn't stop working when connected to the BMW TFT on the SENA 50R. If you use Mesh and do group riding, the 50S/R are the best intercom but they are similar (or identical to the 30K I had after the firmware upgrade). Battery life for me is still inadequate. Several are stating "I ride all day and have no problems", I prefer counting hours that are spent because I don't stop a lot and some people, a "whole day" is not specific enough. On Mesh, yesterday with 4 riders (2x 50R, 2x 30K), music in the background, lasted 5h07mins and 5h19mins respectively, IMO, not enough. If you don't mind riding plugged or charging during lunch, that may be ok for several people. A few glitches here and there, read my review in the "SENA 50R series" thread for more information.
